MetaVia Expands Global Patent Protection for Vanoglipel, Supporting Metabolic and Liver Disease Therapy Through 2035

Patent Portfolio Includes 48 Granted and Pending Patents in the U.S., Europe, Japan, China and other Countries, Providing Protection Into 2035, Unless Extended Further

CAMBRIDGE, Mass., March 12, 2026 /PRNewswire/ -- MetaVia Inc. (Nasdaq: MTVA), a clinical-stage biotechnology company focused on transforming cardiometabolic diseases, today announced a comprehensive global intellectual property portfolio supporting vanoglipel (DA-1241), its novel, orally available G-protein-coupled receptor 119 (GPR119) agonist. This currently includes 48 granted and pending patents across three patent families in the U.S., Europe, Japan, China and other countries, providing protection into 2035, unless extended further.

MetaVia's patent portfolio, exclusively licensed from Dong-A ST Co., Ltd., provides broad protection for vanoglipel itself, how it is manufactured, and its potential use across a range of serious metabolic and liver conditions. Collectively, the patents cover both the core compound and pharmaceutical compositions designed to treat diseases linked to metabolic dysfunction, including Metabolic Dysfunction-Associated Steatohepatitis (MASH) and diabetes.

"Maintaining and expanding a strong intellectual property position is a core element of our strategy to maximize the long-term value potential of vanoglipel," stated Hyung Heon Kim, President and Chief Executive Officer of MetaVia. "These patents reflect the broad therapeutic opportunity for DA-1241 across liver and metabolic diseases and reinforce our commitment to advancing innovative oral treatments for patients who currently have limited options."

About Vanoglipel (DA-1241)

Vanoglipel (DA-1241) is a novel G-Protein-Coupled Receptor 119 (GPR119) agonist with development optionality as a standalone and/or combination therapy for both MASH and type 2 diabetes (T2D). Agonism of GPR119 in the gut promotes the release of key gut peptides GLP-1, GIP, and PYY. These peptides play a further role in glucose metabolism, lipid metabolism and weight loss. Vanoglipel has beneficial effects on glucose, lipid profile and liver inflammation, supported by potential efficacy demonstrated during in vivo preclinical studies. The therapeutic potential of vanoglipel has been demonstrated in multiple pre-clinical animal models of MASH and T2D where vanoglipel reduced hepatic steatosis, inflammation, fibrosis, and improved glucose control. Furthermore, in Phase 1a, 1b and 2a trials, vanoglipel was well tolerated in both healthy volunteers and those with T2DM. In a Phase 2a clinical study, vanoglipel demonstrated direct hepatic action in addition to its glucose lowering effects.

About MetaVia

MetaVia Inc. is a clinical-stage biotechnology company focused on transforming cardiometabolic diseases. The company is currently developing DA-1726 for the treatment of obesity, and is developing vanoglipel (DA-1241) for the treatment of Metabolic Dysfunction-Associated Steatohepatitis (MASH). DA-1726 is a novel oxyntomodulin (OXM) analogue that functions as a glucagon-like peptide-1 receptor (GLP1R) and glucagon receptor (GCGR) dual agonist. OXM is a naturally-occurring gut hormone that activates GLP1R and GCGR, thereby decreasing food intake while increasing energy expenditure, thus potentially resulting in superior body weight loss compared to selective GLP1R agonists. In a Phase 1 multiple ascending dose (MAD) trial in obesity, DA-1726 demonstrated best-in-class potential for weight loss, glucose control, and waist reduction. Vanoglipel is a novel G-protein-coupled receptor 119 (GPR119) agonist that promotes the release of key gut peptides GLP-1, GIP, and PYY. In pre-clinical studies, vanoglipel demonstrated a positive effect on liver inflammation, lipid metabolism, weight loss, and glucose metabolism, reducing hepatic steatosis, hepatic inflammation, and liver fibrosis, while also improving glucose control. In a Phase 2a clinical study, vanoglipel demonstrated direct hepatic action in addition to its glucose lowering effects.
